I was noticing some flickering watching dvds on Ubuntu 8.04 whilst running compiz. The flickering was even worse on those rare occassions I play a game. All this flickering went away when I disabled compiz, however, when enabling compiz again all the settings had been reset to defaults which was really annoying!
Here is the awesome fix for this behaviour, the compiz switch.
So easy to use, and it just works. It makes tip of the week.
